    摘要： A structural body component, such as a rocker panel or rear spoiler, and a method of manufacture. The method may include heating a mixture having a polymer and a blowing agent, pressurizing a cavity of a mold, injecting the mixture into the cavity in a single shot such while exerting backpressure against the mixture as it is injected, and cooling the mixture in the mold to form the component.

    摘要： A method of improving the appearance of foaming injection molding product includes closing the moving mold and the fixed mold and setting a clamping force on the closed mold, wherein a mold cavity is formed between the moving mold and the fixed mold. The method proceeds by inflating the mold cavity with high pressure and high temperature gas until the air pressure in the mold cavity reaches 2-25 MPa and the temperature of the high pressure and high temperature gas is between 60-200° C., then injecting molten resin that contains foaming agent into the mold cavity while continuously inflating high pressure and high temperature gas. After injection completed, stopping inflating high pressure and high temperature gas and simultaneously releasing pressure, wherein the step of releasing pressure includes the step of opening the mold.

    摘要： A method of producing a foam product subjects a body of expanded closed-cell foam, in particular expanded polystyrene particle foam, to a non-melting heat treatment at a temperature above the glass transition temperature of the plastic used to form the foam, in particular polystyrene. The volume of the foam product is reduced by the heat treatment compared with the initial state prior to the heat treatment by a value from a range between a lower limit of 50% and an upper limit of 97%.
